Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The cars engine runs away with my car when I am sitting with my foot on the brake or at very slow idle with my foot on the brake. The problem is one that needs to be recalled. The internet is full of the same complaint for the same year and mileage, ( 29,000-32,000 miles ). I am reaching out to you because my car is at the dealer, nothing has been done to fix the problem, and I refuse to take my car back at this point. I paid cash for this car and this is the second time it has been in for the same problem. On Monday afternoon I pulled into my bank with cars in front of me and beside me. I came to a stop, had my foot on the brake and all hell broke loose. My car lunged forward, my engine was screaming, my speedometer said 80 mph, I had both feet on the brake to not hit the woman in front, my rear wheels were smoking and screaming and my car was jumping side to side because of the spinning wheels and nowhere to go because at this point I am standing on the brake with both feet. Someone screamed turn off the ignition and the moment was over. Courtesy Chevrolet in salisbury md, just called to say the problem didn't throw a code so Cadillac won't pay them to look and fix the problem. If they won"T fix what's wrong they can keep the vehicle and I want my money back and as I told them I won't stop until I get someone to listen and warn others of this problem. I have researched the internet and this is a very serious problem widespread and these cars need to be recalled. My husband says it's probably a problem in the computer that when the precise pressure is applied to the brake, the signal to the engine is go not stop.

After backing the vehicle in to a parking spot I wanted to straighten it out. When I put the car in drive there was a loud shrilling noise (sounded somewhat like brakes peeling) and the car accelerated forward with my foot on the brake. I pumped the brakes in an attempt to stop the vehicle but every time I pushed the brake the car would buck forward. In a matter of seconds the vehicle crashed in to a wall. This whole incident was less than 10 seconds. I would like to note this was a loaner vehicle. I would also like to note that the floor mats for this vehicle were in the trunk of the car and cardboard with plastic wrap over it was being used in their place. I don't know if that had anything to do with this but wanted to make you aware. The vehicle instantly began leaking fluid and had to be towed to the dealership. The tow truck driver made a comment that there was something wrong with the vehicle. Updated 02/07/12

I was driving my sister-in-law's 2008 Cadillac Cts home from work one night in December. I came up to the street out of the mall parking lot and put my foot on the brake to slow down. Suddenly, the engine took off and revved up to around 4000rpms, so much I could hardly hold it with the brakes. I put in park and reached down to feel the floor mat to see if it was on the accelerator. It was not. I turned off the car. The next day, I took it to the GM dealer. I don't think they believed me because they could not repeat the condition. They had me leave the car and they said they would look at it. The next day I picked ut up. They said that they had re-programmed the throttle body control unit. I left with the car and proceeded to exit the lot. Just as I got to the street, it took off again, revving to about 4000 rpms or so. I immediately went back and told the dealer what happened. They stared at each other and shrugged their shoulders. They never fixed the problem. I am convinced that this is a software issue in the throttle control system, just like Toyota is dealing with. If my wife had been driving this car, she could have been seriously injured. This is a very serious problem and needs attention immediately, . it is not just Toyota.

Twice, while driving my wife's 2008 Cadillac Cts, my foot has wedged both on the accelerator and the brake pedal causing me to proceed forward while attempting to brake. The first @, 6 mos ago, caused me to proceed into an intersection narrowly being missed by a vehicle coming from my left. The 2nd occurred @ 1 week ago causing me to just miss hitting a car parked in front. My wife had a similar incident @ 6 mos ago while backing out of a driveway. I have reported both incidents to Cadillac with no further communication from them. They gave me this site when I requested an Agency to report this problem so I might help others avoid being injured. I will not drive my wife's car in the future due to the above incidents and the fear of a more onerous outcome when it happens again.
